I need to replace my plugs. Do I stay with the good ole NGK copper or go with something different? What about changing heat ranges? I know nothing when it comes to this.

Bosch paltinum 4?
Irridium?
E3?

Basically I want the most efficient plug I can get. I want something that will burn the most amount of fuel possible. I am leaning toward the E3 because they claim to make more power using less fuel or so the video on their site claims. Also, would like something that may last a little longer. My bike is not high reving normal cruising rpm is 4500 if that makes a bit of difference.

Are you talking about spark plugs for the car or motorcycle? If you are talking cars I always use Bosch platinum 4 and have great results with them. I tend to get great gas milage when using them. 26 MPG in the Ford Ranger 1998 4 cyl.

OVER? did you say "Over"? Nothing is over until we decide its over, was it over when the Germans bombed Pearl Harbor? Hell No!!!

If you heare anything about Brisk racing plugs dont use them I have had two bad sets so far on my bike.

E3 are $6 each and I only need 3. I put the Bocsh in the Camry and gained 1MPG whooopie

A 1mpg difference can easily be attributed to something as simple as air temperature. This was very evident on my trip to Barber. I gained several mpg later in the trip on my second tank of gas when it was hot compared to the first tank which was burned up when it was 20-30 degrees cooler.

Standard NGK work just find. I've compared standard ones to iridium on the dyno. No difference.

Thanks.

I'll stick to the NGK. They are cheap. I don't really care if I gain power, only economy and longevity.
